Here's what I posted on the official forums, so they can at least see how some of us feel about it.

*Edit - some folks have pointed out the added sparkler effect is from a trinket, which means that the "new" DA graphic is basically the same as PWS (which would be very insulting if true) or that hopefully there's a bug of some kind on the PTR (maybe the new graphic file isn't actually loaded or is bugged). I shall husband my ire until we find out more details....

TLDR: New Divine Aegis graphic is underwhelming (sparklers on top of a retreaded PW: Shield? really?) and seems to contradict the reason given for the removal of the original (imho: much better) Divine Aegis graphic.

Background:
I was extremely disappointed when Blizz removed the previous graphic for Divine Aegis. Imho, it was one of the better shield type affects and really helped set the Disc priest effects apart. Additionally, it actually served a useful purpose since it was a good visual indicator of a Divine Aegis affect vs a Divine Shield affect. And I did i mention that it just looked good??

I, along with what seemed like hundreds of others, expressed my dissappointment in this unannounced change, and even more so that instead of waiting until they had a better graphic, they just re-treaded the Power Word Shield graphic (which is a very underwhelming graphic). The justification given was that the old graphic " was too visually distracting" and "too shiny" (which I still find very difficult to follow, given the multitude of other, flashy graphics in the game, which i like!). Priest were assurred that a new and distinct graphic would eventually replace the placeholder graphic.

Flash forward to the 4.3 PTR:
Just watched a video showing the "new" graphic. It's Power Word Shield with strobbing sparklers..... Not only is it terrible compared to the slickness of the old Divine Aegis (barely a step up from PWS), but it seems EVEN FLASHIER than the old one. And, in what feels like insult to injury, it does not even appear to solve the supposed "too flashy" problem that caused the old graphic to be removed.

Suggestion:
Divine Aegis should look like some type of SHIELD or force bubble (one of the hallmarks, imho, of the old graphic). Bring back the Round bubble affect of DA, but perhaps with the shimmer/flash removed.

What? The bubble in the video is the same as live, namely the PW:S bubble. The new effect isn't active on the PTRs yet.

so the sparkle effect is just a trinket?!

In that case, it makes the "new" graphic even worse (almost insulting). I hope the patche notes are either wrong (the graphic hasn't been loaded yet) or there is a bug with the new graphic and it is not displaying

The sparkle effect is the trinket, the "new" bubble in the video is the same as 4.2 live. The new Divine Aegis effect is NOT ACTIVE on the PTRs.
